IMPROVEMENT IN MACHINES FOR ATTACHl NG AND TRIMMING HEELS.

Specification forming part of Letters Patent No. 166,795, dated August17, 1875; application filed June 24, 1875. I

To all whom it may concern:

Be it known that we, GORDON MCKAY, of Cambridge, Middlesex county,CHARLES W.

' GLIDDEN, of Lynn, Essex county, and HAD- LEY P. FAIRFIELD, of Boston,Suffolk county,

all in the State of Massachusetts, have inventment of the heel seatclamp to correspond with heels of different sizes. The jack-holdingplate is carried by a reciprocating bar connected with a walking-beamoperated by compressed air, acting through a cylinder, piston, and link.The heel to be attachedto the shoe or boot, and composed of layers ofleather or of other material, has a series of nails projecting from itslower side, and these nails are entered in the series of holes in theheel-supporting plate, provided with a series of naildrivers, which meetthe ends of the nails as the heel-support is depressed by the action ofthe shoe-sole on the heel, the sole and shoe being depressed through theaction of the walking-beam. The nails, by this movement, are driventhrough theheel into and through the sole, and clinched by strikingagainst the bottom of the last, and at a single operation. After thenails are driven the heel cutting or trimming mechanism is thrown intoaction. The heel-trimming knife is guided about the heel-support in aheelshaped path, being governed by cam-grooves in a plate, into whichproject pins from a turn-table. The trimmingturn being carried by, andis free to rotate in,

a rotary reciprocating carriage having movement imparted to it by meansof projections on a cross-plate, which enter openings'in the the center,about which the turn-table turns,

so as to properly and smoothly cut the heel. Figure 1 represents a sideelevation of a machine embodying this invention, the cylinder being insection. Fig. 2 is an opposite side view of part of the machine, withthe aircompressing apparatus in section, the compressed air-receiverbeing broken away, and with a detached part of the receiver shown insection above the figure. Fig. 3 represents the holding and adjustingdevices for the clamp. Fig. 4 is a partial section across the lower partof Fig. 1. Fig. 5 is a top view of Fig. 1, with the upper part of theframe of the machine and the walking-lever and last and its supportremoved or broken away. Fig. 6 represents the lever for operating thevalve mechanism leading to the cylinder. Fig. 7 is a partial sectionthrough the heel-support, and devices for operating the heel-trimmingmechanism. Fig. 8 is a top view of partsshown in Fig. 7. Fig. 9 is aview of the heeltrimming knife removed from the knife-holder.

Fig. 22, a view of thelast, and Fig. 23 the valve of the air-compressor.knife holder is carried by this turn-table, it in j A is the frame ofthe machine, having projecting portions to a, forming guides andbearings, and properly shaped to support the wvoi-king parts of themachine.

Power is applied to the main shaft B of the machine,

through a handle or pulley, in any well-known way, a pinion, b, thereonengaging a pinion, b, on a second shaft, 11 having a crank, b connectedby link 0 (preferably in two parts, 0 0 joined by a screw 0 with theplunger or piston D of the air-compressing pump, adapted to supply thereceiver E with compressed air. This piston consists of a head or seat,cl, screwed into the cylindrical portion of the piston, and has a valveprovided with a series of holes, 73 Fig. 23, and a plate, j, seated atthe top of head'd, yet being free to rise and fall about a central guideor plug, d, which is adapted to fit a correspondinglyshaped opening, LP,in a support, 0, for the valve 6 A leather or other washer, h,perforated with holes, rests under plate j, and a cup-like packing, lsurrounds d. When the piston descends, the valve 6 closes, opening d,and plate. j rises a little from its seat, permitting air topass throughopenings 6 above d, and into the chamber e As the piston rises, theplate j? is held to its seat, valve 0 rises, the air in the'chamber c iscompressed or forced into the receiver E, and the plug d acting withinthe opening 6, forces all the air within the chamber 6 into the chamberor receiver E. The piston F, fo'rimpartin g motion tothe parts carryingthe boot or shoe to be heeled, is moved upward by the action of thecompressed air of the receiver, such compressed air being conductedthrough an opening,f, into a pipe, f which, by suitable el-' bows orconnections, delivers it at opening f into the valve-chest Gr, providedwith a doubleheaded valve, 9, carried by a spindle, g having an attachedyet adjustable block, 9 engaged by the forked end of the pivoted leverH, for operating the valve-rod g, and slotted at its other end toreceive a pin projecting from a pivoted lever, h, connected by links k kwith treadles or levers I i, pivoted at i. A passage, i leads fromvalve-chamber G into the cylinder J, and under the piston F. With thevalve gin the position shown in Fig. 15, the passage 1' is free tocommunicate with the atmosphere, and the weight of the piston F andwalking-beam is such that the piston will descend or remain at thebottom of the cylinder J Now, if the lever I is depressed, lever Handthe valve-rod g will be depressed thereby, bringing the face 1 of thevalve 9 'below the passage i and then the compressed air will enter fromthe pipe) of the receiver, through the valve-chest and under, and willquickly raise the piston F, which, through its attached link j, movesthe walking-beam j, having its fulcrum j resting in bearings at a Theheel support or plate K has a series of holes, 7 7, to receive the nailspartially entered or started into the lower portion of the heel to beattached to a shoe, but projecting from the heel, and the box k, onwhich the plate rests and is pivoted, contains within it a series ofdrivers, is, resting on a loose plate, 70 supported on a stationaryheel-shaped plate, L, shaped to conform to the shape of the heelsupportand box K 70. Thebox and supporting-plate k are sustained on a rod, 1,which passes through plate L, and is sustained on a shouldered pin, lresting on a spiral spring, 1 sustained in a chamber of a post, P, whichmay be raised and lowered in its hearing at a by means of a' screw, M,seated at one end on the frame A, and provided with screw-threads toengage screw-threads in an opening in the post 1". By the hand-wheel onthe screw the post may be raised or lowered to adapt the mechanism tooperate on heels of different thicknesses.

This construction of' the heel-support, box, loose plate, and rodlenables the heel-support to be easily and quickly removed from theturn-table to permit the application of another support and box anddrivers adapted for different-sized heels, and in doing so the looseplate 70 retains the drivers in position, and prevents them from beingthrown out of the box k,- but this feature, as well asthe provision foradjusting the trimming-knife, we do not herein claim, as they form thesubject-matter of an application for patent made by Charles WoodburyGlidden and Stephen Allen Simmons.

Supposing the nails projecting from a heel, as described, and insertedin the holes in the plate K, then-the descent of the heel and box It,the heel being kept in contact with the plate K, and the drivers 70being then immovable, will cause the drivers to act onthe ends of anddrive the nails in and through the heel, and into and through the soleof the shoe, provided the sole is kept in contact with the heel as thelatter descends, and the nails striking against the metallic last willbe clinched I The mechanism for depressingthe shoe and keeping its solein contact with the heel while the heel is depressed, and the nails aredriven through the heel into the sole, maybe described as follows: Thebar N, guidedin projection a.

of the frame, and made angular or otherwise to prevent rotation, isconnected, by means of a stirrup, n, with the end of, and isreciprocated by, the walking beam. Torthe lower end of bar N isadjustably attached a jackholding plate, n grooved to receive theflanged plate 12 of the bar 0, which carries the last or shoe-holder,(see Fig. 22,) having an adjustable toe-piece, 0, and a heel part,-oprovided with'sockets to receive the pins projecting from thelast-carrying bar 0. The toe-piece is pressed forward by a springsurrounding its carrying-rod 0. Attached to plate n is a T-. shapedguiding-ledge, embraced by a corre spondingly shaped slide, P,adjustable by means of a screw, 1), in the direction of the arrow 2,Fig. 3. On the under side of this slide is a T-shapcd ledge, p crossingit at right angles, and this ledge is embraced by thecorrespondingly-shaped upper end of the arm 12*, having at its lower enda guide-box receiving the guide-plate q, having the forked slotted-eyedsupport g of the heel-seat clamp Q, provided with ears'q entering theslotted eyes in the support q, the clamp being in this way supported andadjustable in position, to allow the position of the clamp, which is ofa size to conform to the size of shoe being heeled, to be adjusted topresent the sole at the heel part exactly in the proper position withrelation to'the heel, so as to properly attach the heel. I In boots orshoesmade up rights or lefts it is necessary to have what is called aright and left adjustment of the shoe or boot with relation to the heel,and for this purpose a forked piece, It, is attached to the bar N, andis provided with two set-screws, r, to hear one. projection, 13 fromplate a and by turning these screws the plate maybe turned to the rightor left, so as to set the heel correctly. For this class of work the toeshould be inclined toward that side of the shoe hollowed to fit theinside of the foot.

The clamp Q for the shoe is carried by the arm 19 connected with thejack-holding plate a, and the clamp is therefore moved when the ..platea is adjusted. If the arm 19 were not so connected with the plate 02then the clamp would bind the heel-seat unevenly under differentadjustments of the plate W. The clamp Qhas hinged wings or levers 3 3,

thrown inward by a spring, 4, and the clamp and wings have thin plates5, adapted to enter between the sole and bent portion of the counter,the wings and their plates hugging the heel-seat closely.

.In Fig. 10 the clamp is shown as applied to a shoe, the heel has beenattached, and the heel-trimming knife (1 is shown as in position, and ashaving cut a portion of the heel.

The driving-shaft B has a friction-wheel, S,

and near it, on another shaft, is a frictionpulley, s, which is moved,when desired, by bringing between the two pulleys a third pulley, sworked by a treadle, 3 When the pulley s is not in contact with theother pulleys its treadle is raised, and the brake T holds the wheels infixed position. This wheel is intended to rotate once, and then to havean interval of rest, so when the lever s is depressed to engage thewheels a lever, .15, is

thrown in position, as shown in Fig. l, bearing on a lug on lever 8 andholding that lever down, and the wheels remain so engaged until a pin onwheel 8 (shown in dotted lines, Fig. 1) strikes the lever 17, when thelever is turned, and the treadle is allowed to rise under the action ofits attached spring 19. The shaft 2? of wheels has a crank, U, providedwith a crank-pin, u, adjustable by a screw, it entering a slot, W, in aslotted radius-bar, V, forked at top, and fitted to a pivoted block, 1;,on a carriage, 0 arranged to run on a guideway, 11 One rotation of thecrank gives one complete vibration to the radius-bar, its extent ofmovement depending on the position of the crank-pin a, and one suchvibration throughcords \V, connected with a pulley on the forkedcross-plate w, and passing about an adjustable pulley, w, on a movablestandard,

turns the cross-plate around the heel-support and back. this being the.movement required to trim the heeland return the trimming-lmife to itsstarting position. This movement takes place after the heel is attached,and. While the shoe and heel are held down. From the crossplate 10project lugs 20 which'enter slots in a movable carriage, X, providedwith a turntable, 00, having pins 6 8, Fig. 19, entering grooves 9 10,Fig. let, in a stationary plate, :0. These grooves are shapedsubstantially as shown in Fig. 14, the groove 9 receiving the pin 6, andthe groove 10 the pin 8. The groove 10 governs the shape of the heel,and thegroove 9 controls the presentation ofthe knife to the heel, sothat the angle at which it meets the leather on its travel about theheel shall be such as to cut with the greatest ease and advantagepossible, and therefore the outer groove is made of a shape differingsomewhat from groove 10, and is adapted, in each case, to the particularshape of the heel to be trimmed.

The trimming-knife'holder a is adapted to slide on a T-shaped ledge, battached to the juriously dip into or leave the leather, or cut the heelroughly. The knife 01, curved to properly shape the heel, is adjustablelaterally. in its holder or, to adapt it to heels of different sizes, itbeing carried by a slideplate, 0 adjusted by a screw and nut, f. Theplate 0 has a rod, n fitted to its ears, and this rod is entered in theopening 0 in a lug attached tothe lower end of the knife, this rodserving as a fulcrum for the knife. The knife 61 is made adjustable withreference to a block, 19, Fig. 9, and to the sole-gaget, by means of ascrew, 9 to regulate the depth of the cut or the quantity of material tobe removed from the sole and heel. This block pf carries a gage, 1",adjustable by means of a set-screw, s, the gage being adjusted to strikethe end of the clamp Q, and throw the upper end of the knife outwardjustas the knife is finishing its cut, to prevent the knife from cuttingthe shank of the sole. The sole-gage is shown by the letter i, Fig. 9;it bears against ,the

edge of the sole as the trimming-knife is moved the outside lift on it,and then force the lift,

by the descent of the heel and shoe, onto the projecting heads of theheel-nails. In Fig. 21

the turn-table and knife-carrying guide b are in the position theyoccupy with reference to clamp Q is used chiefly in the manufacture ofshoeshaving cloth uppers, and it may be used with advantage with allkinds of shoes; but in the manufacture of shoes having leather countersit need not be used. In such case the shoe is put over the last, asbefore "described, and,.instead of the solegage t the rand-crease gageand guard "a Fig. 24., is

placed in advance of the trimming-knife, its

edge b resting in the rand-crease, and its lip c overlapping the uppercorner of the knife, preventing it from cutting the counter.

Rising from the stationary plateL is a pin, 20 which, in connection withrod 1, keeps the heel-support and box in correct position. In additionto its function of a guide, this pin also serves as a locking device forthe plate a its upper end entering the opening a in the plate, therebyholding it in position on top of the support K, so that it is in correctposi-' tion with reference to the knife which turns the heel after thetop lift is added.
